It's smart to be weary of parvo, but I think it depends on your local area and how prevalent parvo may be. We walked our doodle, Dave around the block in our neighborhood starting a very young age. We also had puppy playdates (within our own yard/home) with pups that were at the same stage of vaccinations. We made an effort and invited alot of our friends over to our house to meet him when he was young. He's such a well adjusted, friendly 9 month old doodle now, and I feel like it's because we did start socializing him at such a young age. We are so shocked to have met so many dogs whose owners say "I'm sorry, he doesn't do well with other dogs." It's such a shame because one of the coolest thing to see is your dog happily frolicking with other dogs.
